Aim: The aim of this study was to investigate the measurements of the mandibular canal in different
patterns of reabsorbed alveolar ridges, using multidetector computed tomography in order to
evaluate the relationship of the mandibular canal with the cortex of the mandible remains.
Central cross-sectional slice of 30 edentulous alveolar ridges in the mandibular first molar region
of otherwise healthy patients using multidetector computed tomography were analyzed. Horizontal
and vertical lines were performed tangent to the corticals of the mandible and mandibular canal.
Fisher’s exact test, Spearman test and linear regression were used for statistical analysis.
Significance level for all statistical tests was 95%.
Results: The height of the mandible and the
distance of mandibular canal to superior cortical in males were significantly higher when compared
with females (p<0.05). When the height of the mandibular bone was correlated to the classification
of edentulous jaws, significant differences were observed when comparing the three types (III, IV
and V) as well as between III and IV type.
Conclusions: The results of the present study show
that the measurements for dental implant placement in the posterior region of the mandible are
affected by the different patterns of bone resorptions. It was also demonstrated the importance of
the computed tomography in the process of planning dental implant placements.
